1. VOLUME
The volume of a 3D shape is the amount of space within that solid.

2. Count
the
unit3

3. 1 cube = 1 unit3

4. How many unit3 are there?
15 unit3

5. How many unit3 are there?
12 unit3

6. How many unit3 are there?
13 unit3

7. How many unit3 are there?
10 unit3

8. Volume of Cube Shape Cubes counted Length, l Breadth, b Height, h
Volume of shape =

9. Look at this cube carefully

10. 1st layer
16 unit3
1st + 2nd layer
1 6 unit3
+ 1 6 unit3
3 2 unit3

11. Counting unit3 is just piece of cake..
1st + 2nd + 3rd layer
3 2 unit3
+ 1 6 unit3
4 8 unit3

12. 1st + 2nd + 3rd + 4th layer
4 8 unit3
unit3
6 4 unit3

13. 4 unit
4 unit
4 unit
Total cubes: 64 unit3

14. Volume = l × b × h = 4 unit × 4 unit × 4 unit = 16 unit2 × 4 unit

15. The table you formed Shape Cube Cubes counted 64 unit3 Length, l
Breadth, b
Height, h
Volume of shape,
l × b × h

16. Look at this cuboid closely

17. 1st layer
9 unit3
1st + 2nd layer
9 unit3
unit3
1 8 unit3

18. 1st + 2nd + 3rd layer
1 8 unit3
unit3
2 7 unit3

19. 1st + 2nd + 3rd + 4th layer
2 7 unit3
unit3
3 6 unit3

20. 4 unit
3 unit
3 unit
Total cubes: 36 unit3

21. Volume = l × b × h = 3 unit × 3 unit × 4 unit = 9 unit2 × 4 unit

22. The table you formed Shape Cuboid Cubes counted 36 unit3 Length, l
Breadth, b
Height, h
4 unit
Volume of shape,
l × b × h

23. Volume = length × breadth × height
Therefore,
Volume = length × breadth × height

10m
1000m3

27. Calculate the volume of the cuboid below
Question 5
Calculate the volume of the cuboid below
10cm
3cm
90cm3

28. Volume = length × breadth × height
Conclusion(song)
How do you calculate volume of cube and cuboid?
Volume = length × breadth × height

29. Extension Question
How many small boxes fit into the big one? 3000  ……..80 boxes

30. 1 litre = 1000ml also 1 litre = 1000cm3 Did you know?
Therefore  1ml = 1cm3
